[Impact]
Starting with 5.13 we've incorrectly dropped the following sauce patch:
UBUNTU: SAUCE: overlayfs: fix incorrect mnt_id of files opened from map_files
This patch seems to be required to use overlayfs on top of shiftfs and without this patch we may break containers that rely on shiftfs (using zfs/ceph as storage pool w/ shiftfs enabled).
[Test case]
No specific test case provided.
[Fix]
The original SAUCE patch relies on AUFS in order to use vma->vm_prfile, but we're not providing AUFS anymore in jammy,.
The fix consists of re-apply this patch with a little refactoring to be dependent on CONFIG_AUFS_FS.
[Regression potential]
This patch is touching overlayfs, so we may see potential regressions in overlayfs.
